The Peugeot 9HK (DV6ETEDM) is a 1,560 cc, inline‑four turbo‑diesel engine produced between 2015 and 2021. It features a 16‑valve DOHC layout, common rail direct injection, and a variable geometry turbocharger (VGT), delivering 88 kW (120 PS) and 300 Nm of torque. This compact unit was designed for efficiency and responsive low‑end performance in Peugeot's global small car and SUV lineup.
Fitted to models such as the 208, 308, and 3008, the 9HK was engineered for urban agility and fuel economy, offering strong torque from low revs for relaxed driving. Emissions compliance for its production period was achieved through a diesel particulate filter (DPF) and selective catalytic reduction (SCR) with AdBlue injection, enabling adherence to the stringent Euro 6 standard across all markets.
A documented reliability concern involves premature failure of the exhaust gas recirculation (EGR) cooler, potentially leading to coolant contamination and overheating. This issue, referenced in PSA Group Service Bulletin 16D011, is often attributed to thermal stress and internal corrosion. The cooler design was revised in later production runs to improve durability.
Production years 2015–2021 meet Euro 6 standards (VCA UK Type Approval #VCA/PSA/9HK).
The Peugeot 9HK (DV6ETEDM) is a 1,560 cc inline‑four turbo‑diesel engineered for compact cars and SUVs (2015-2021). It combines common‑rail direct injection with a variable‑geometry turbocharger to deliver strong low‑end torque and high fuel efficiency. Designed to meet Euro 6 standards, it balances urban drivability with low emissions.

The VGT turbo provides strong low-RPM torque ideal for city driving but demands strict 20,000 km or annual oil changes to prevent chain wear. PSA B71 2312 (5W-30) oil is critical for turbo and emissions system longevity. The Denso fuel system requires ultra-low-sulfur diesel (ULSD) meeting EN 590 standards. The EGR cooler is susceptible to failure; monitor for coolant loss or white exhaust smoke and replace per PSA SIB 16D011 if symptoms appear. The SCR/AdBlue system requires regular top-ups to prevent limp mode.
Oil Specs: Requires PSA B71 2312 specification (PSA Service Schedule). Equivalent to ACEA C2/C3.
Emissions: Euro 6 certification applies to all 2015–2021 models (VCA Type Approval #VCA/PSA/9HK).
Power Ratings: Measured under ECE R85 standards. Output is consistent across model range (PSA Group PT-2018).

The Peugeot 9HK (DV6ETEDM) was used across Peugeot's EMP2 platform with transverse mounting. This engine received platform-specific adaptations-reinforced mounts in the 3008-and no significant facelift revisions occurred during its production run, ensuring broad parts compatibility. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the flat machined surface at the front of the cylinder block, near the gearbox flange (PSA Repair Manual 9HK). The 8th digit of the VIN is 'S' for this 1.6 BlueHDi 120 engine variant. Visually, it can be identified by its black plastic rocker cover and the Honeywell VGT turbocharger mounted at the front. Critical differentiation from the lower-powered DV6DTED: The 9HK has a higher torque output (300 Nm vs 254 Nm) and features an SCR/AdBlue system. Service parts, particularly the EGR cooler and injectors, are specific to the 9HK and not interchangeable with other DV6 variants without verification.
The 9HK's primary reliability risk is EGR cooler failure, with elevated incidence in vehicles subjected to frequent short trips or high thermal loads. PSA internal data indicated a notable failure rate before 100,000 km in affected batches, while owner reports frequently cite coolant loss and overheating. Thermal cycling and infrequent highway driving increase cooler stress, making driving habits and prompt replacement critical.
Analysis derived from PSA technical bulletins (2015-2021) and owner-reported failure data (2018-2023). Repair procedures should follow manufacturer guidelines.
